Abrasive wear amount estimate for 3D patterned tire utilizing frictional dynamic rolling analysis

摘要

In this paper, a numerical technique for predicting the wear amount of automobile tire is presented. A power function wear model derived based on the laboratory testing of rubber abrasion is adopted to correlate the wear rate of tread rubber blocks with the frictional energy dissipation, and the driving and loading conditions of the tire in the outdoor wear test are extracted from the virtual driving simulation using ADAMS. The tire frictional energy rates produced in each driving mode are computed by the frictional dynamic rolling analysis of 3D patterned tire model. Numerical results are also given to illustrate the theoretical work.
